PREFILLED SYRINGE

摘要

A prefilled syringe includes a syringe cylinder (2), which has an open axial side, closed by a plunger, and another side closed by a Luer lock connection (4), molded on an end wall. A flowable medium (8) fills the syringe cylinder (2), a soft-elastic stopper (9) closes at least the Luer (5), and a tamper-evident closure (15) surrounds the outside of the stopper (9) and which has a predetermined breaking point. The syringe cylinder (2), the end wall (3), and the Luer lock connection (4) are formed as a single piece in the form of a transparent injection-molded plastic part. The tamper-evident closure (15) includes the same or a similar plastic as the syringe cylinder (2) and is welded to the end wall (3) of the syringe cylinder (2). The welding connection forms the predetermined breaking point, and the stopper (9) is integrated into the tamper-evident closure (15).

主权项

1. A prefilled syringe comprising:
a plunger; a syringe cylinder with one axial side with an opening closed by the plunger, and which comprises a Luer lock connection comprising a Luer at another axial side, said Luer lock connection being integrally formed on a face wall of the syringe cylinder, closing off the syringe cylinder; a flowable medium filled into the syringe cylinder; a soft-elastic plug which closes at least the Luer and with a tamper-evident closure which at least partially surrounds the plug to an outside of the plug and has a predetermined breakage location, wherein the syringe cylinder, the face wall and the Luer lock connection are formed as one piece as a transparent plastic injection molded part, the tamper-evident closure comprising a same type or similar type of plastic as the syringe cylinder and being welded to the face wall of the syringe cylinder via a weld connection, wherein the weld connection forms the predetermined breakage location and the plug is integrated into the tamper-evident closure.
